Conaway, who starred in TV's "Taxi" and the movie musical "Grease," has pneumonia and sepsis, a potentially deadly blood poisoning caused by a bacterial infection, Brock said Monday. The next 48 hours are considered crucial.
To aid his recovery, Conaway was in a medically induced coma at the Encino Tarzana Medical Center, Brock said.
In 2008, the actor aired his battle with addiction on TV's "Celebrity Rehab." Conaway has struggled with back pain and repeated operations, Brock said.
